ZnO/CdS:Zn异质结构光阳极的制备及性能研究
Preparation and Properties of ZnO/CdS:Zn Heterostructured Photoanodes
摘要
Abstract
ZnO nanosheet arrays with highly exposed high-energy facets were successfully prepared on FTO conductive glass using a hydrothermal method.Zn doped CdS nanoparticles were deposited on the surface of ZnO nanosheets via successive ionic layer adsorption and reaction technique,forming a ZnO/CdS:Zn heterostructure photoanode.The crystal phase,microstructure,optical properties,and photoelectrochemical properties of the prepared photoanodes were systematically characterized and analyzed using X-ray diffraction,scanning electron microscopy,ultraviolet-visible absorption spectroscopy,and a three-electrode photoelectrochemical testing system.The results indicate that Zn doped CdS nanoparticles are uniformly and densely deposited on the surface of ZnO nanosheet arrays.As the number of successive ionic layer adsorption and reaction cycles increases,the light absorption range of the films gradually extends into the visible region,and the photocurrent is significantly enhanced,reaching up to 6.25 mA·cm-2.The study demonstrates that the construction of heterostructures combined with elemental doping synergistically promotes a remarkable improvement in the photoelectrochemical property of the films.关键词
